vided.

Another object of the invention is to provide a new and improved manner of securing together the stiles and rails of'metallic sash flames.

Other objects will be in part obvious and in art pointed out hereinafter.

features of construction, combinations of 'elementsand' arrangement of parts which will be exemplified inthe construction herein described and the scope of the application of whichwill be indicated in the appended claims. a

\ In the accompanying drawings, wherein is shown one of t e various possible embodi-- ments of my invention, Fi ure 1 is a view in elevation of a portion oi a metallic sash showing the same; Fig. 2 is a similar view showing the lower portion of a sash stile constructed in accordance therewith; Fig. 3' is a view in perspective-showing the manner of constructing the bottom rail "of the sash;

Fig. 4 is a similar view of the portion of they sashpstile'shown in Fig. 2; Fig. 5 is a view in t0, ,elevation of the inner side of the lower por- 6 is a similar view tion of the sash stile; Fig. 7 is a transof the outer ide thereo verse sectionalview taken through the botstructura ingly strong and rigid construction, soon dishe'invention accordingly consists in the tort it from its original shape and cause it to bind in its frame when raised or lowered.

Such defects, which are prevalent in prior constructions, I have remedied by the construction disclosed herein, and it should be apparent from the followin that sashes constructed in accordance with this invention, while capable of withstanding severe, strains without distortion, are yet of exceedingly I sim leand light construction.

eferring now to the drawings, wherein I have shown but a portion of a sash constructed in accordance with my invention, 1 denotes the lower left-hand portion of the to illustrate my invention, as the remaining joined portions of the sash are similarly constructed.

An end portion of one of the side stiles of the sash is shown at 2. This stile isshown as comprised by a hollow metallic member, a portion of which is outwardly set to form a shoulder 3 against which the glass abuts when seated in the frame. The outer edge ortion 4 of the stile is depressed to form a on itudinallyextending groove 5 which exten s the entire len th of the stile. Por- "tions of the inner surface of the inwardly depressed portions are folded back into engagementwith the inner suriae'es of the lateral sides of the stile as shown" at 6, such construction resulting in the walls of the recess being of double thickness. The depressed portion 4 of the stile is extended beyond the end thereof as shown at 7, and apertures 7 are formed therein for the reception of rivets or other devices for attaching the same to the rail. The rails of the sash, one of which is shown at 8, are also comprised by hollow metallic members having outwardly set shoulders 9 shaped similarly to shoulders 3 of the stiles, and at their outerends have the material at their up er and lower portions cut away to provide ateral flan es 10. Between these flanges is received the extended portion 7 of the stile, and inasmuch as this portion is inwardly oiiseta distance equal to the thickness-of the sheet metal of which the sash is constructed, the outer surfaces of flanges 10 will coineflush with the outer face of the. stile, as shown in Fig. 1. The flanges 10 of rail 8 are provided with openings 11 which re ister with those of the extending portion of the stile, and through these regissash, such showing being deemed. sufiicient'.

sur-

tering openings are provided with joints capable of withvided a construction wherein are realized,

among others, the various ends and objects herein set forth. The rails and stiles of the sash, while of exceedingly light construction,

. standing great stresses. without becoming loose or distorted. Such joined portions are, moreover, exceedingly neat in appearance. The. portions of the stile which are folded back against the inner lateral surfaces thereof result in the walls of the longitudinally-extending recess being of double thick-- ness. This construction also adds to the strength of the structure. i

As many changes could be made in the above',construction and many apparently widely different embodiments of my invention could be made without departing from .the scope thereof, I- intend that all matter contained in the above description or shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limiting sense. I desire it also to be understood that the languageused in the following claims is intended to cover all of .the generic and specific features of the invention herein-described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.

Having described my invention, what I -claim as new and desire to secure by Letters Patent is:

1 In sash construction, arail provided with end flanges, a stile formed of a hollow metallic member a portion of which is depressed and folded back upon other portions thereof, said folded-back portion being extended'beyond the ends of the stiles and in serted between the flanges of the rail, and means for securing said extended portions to said flanges.

2. In sash construction, a hollow metallic for securing said parts together.

v5. In sash construction, a rail formed rail havin portions thereof removed from its upper an lower end portions to form lateral flanges, a stile comprising a hollow metallic member a portion of which is depressed and folded back upon other portions thereof, said folded-back portions being extended beyond the ends of the stile and. inserted between the flanges of the rail, and means whereby said extended portion and said flanges may be secured together. V

3.- In sash construction, a hollow metallic rail havin portions thereof removed from its lower end portions to form latupper and eral flanges, a stile comprising a hollow metallic member aportion of which is depressed and folded back upon other portions thereof .to form a longitmidinally-extending recess therein, said folded-back portion being extended beyond the end of the stile and inserted between the flan es of the rail, said flanges and said exten ed portion having registering openings, and means extendin through said openings adapted to secure sai parts together.

4'. In sash construction, in combination, a rail provided with end flanges, a stile comprising a hollow metallic member a portion" of which is depressed and folded back upon other portionsv thereof, said folded-back portion being extended beyond the end of the stile and inserted between the flanges of the rail, the outer surface of said stile and the outer surfaces of said flanges coming flush, with each other, and means-extending between said extended portion and said flanges with end flan es, a stile comprising a hollow metallic meni er, said stile having inwardlyoflset integral end. extensions adapted to be,

embraced by the flan es of said rail, and means for securing sai inwardly-offset portion and said flanges to ether. i
